There's a lot more to X than the video memory and pixmaps. In my case (this is X.org 6.9.0 on 6-stable/amd64 but the principle is the same), I have 32MB video RAM, 28MB pixmaps and ps report that X is using 78MB - a difference of 18M. If I look at the process memory map (see procfs(5)), the breakdown is: 38MB vnode backed (mostly shared libraries) 32MB device (video memory) 6.75MB swap + default (malloc'd space, stack etc) This suggests that X is storing a lot of pixmaps in video RAM (for efficiency). --=20 Peter Jeremy --Fba/0zbH8Xs+Fj9o Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQFD4bCn/opHv/APuIcRAn32AKCrMlzMD3dsVV2bH3FwN04Eto+UcwCeMri0 d4WUc7lCxw/mutMGSd1Nmrw= =AIUv -----END PGP SIGNATURE----- --Fba/0zbH8Xs+Fj9o--
